Abstract: PURPOSE: An apparatus for measuring a microwave distance using two or more reference line is provided to improve the measurement accuracy, to simplify the construction, and to reduce the production cost. CONSTITUTION: A voltage control oscillator(20) outputs a microwave signal. The microwave signal is transmitted via a switch(32) to an antenna(30). The switch is selectively switched to any one of a first contact point(S1), a second contact point(S2) and a third contact point(S3) via a circulator(31). An electromagnetic energy radiated from the antenna is reflected to an obstacle, and is returned to the antenna after a delay time. The delay time is proportional to a distance to the obstacle. When the reflected signal is reached to a mixer(40), the mixer(40) generates a frequency difference corresponding the product of an output of the oscillator, the delay time, and a modulation factor. The frequency difference is a beat frequency. When an output of the mixer passes a low threshold passage filter(50), a middle frequency having the beat frequency is obtained. After being converted to a frequency range, the middle frequency is saved in a memory(80). The memory is connected with a calculator(90) to display a measurement result using a signal processor(100).

Abstract: PURPOSE: A method for forming a TFT of S-RAM device is provided not only to form a gate insulating layer as a silicon nitride layer but also to prevent loose contact. CONSTITUTION: In forming a silicon nitride layer(14) as a gate insulating layer of a TFT, the silicon nitride layer is formed only on the surface of a gate electrode(13) without an additional etching process. The silicon nitride layer(14) is not located between an interlayer insulating layer(12) and an interlayer planarization layer(20). At contact hole etching process, a contact hole(H) with a good vertical profile is formed because the etching selectivity between the silicon nitride(14) and the interlayer insulation layer(12) and planarization layer(20) doen't bring about the protrusion of the silicon nitride layer(14). Therefore, it can easily bury metal wiring in the contact hole and prevent loose contact.
